The invention discloses an intelligent retrieval method based on geocoding and dynamic indexing. Sensor and time phase information are added into the conventional pyramid structure, and dynamic coding is performed on the pyramid structure through different distribution situations of multi-source remote sensing data, so that fusion and indexing of the multi-source remote sensing data are realized, and real-time quick access of the multi-source remote sensing data is realized; meanwhile, local update of different sensor data at different time periods can be realized rapidly through a multi-source remote sensing data pyramid structure, the data maintaining difficulty is lowered, and the application value of the multi-source sensing data is increased. Moreover, a wavelet-based data compression algorithm is adopted in a process of generating the pyramid structure, so that the storage and transmission efficiencies of the multi-source remote sensing data are increased effectively; massive multi-source remote sensing data is organized and visualized on a digital earth, so that real-time fusion visualization of different scales, different sensors and different time phase data is realized, and online application and shared distribution difficulty of the multi-source remote sensing data is lowered.
